The cost of Forever stamps will increase by 1 cent on January 22, 2012. This means sending a First-Class letter will soon cost 45 cents. This is the first price increase for Forever stamps since May 2009.

Once purchased, Forever stamps can always be used to send a one ounce, First-Class letter, no matter how many times the price of the stamp changes in the future. You do not need to add an additional 1 cent stamp.

Other First-Class mail prices are also increasing:

• Letters (1 oz.) will cost 45 cents. This is a 1-cent increase.
• Additional ounces for letters will remain unchanged at 20 cents.
• Postcards will increase 3 cents to 32 cents.
• Letters to Canada or Mexico will cost 85 cents. This is a 5 cent increase.
• Letters to other international destinations will increase 7 cents to cost $1.05.

Prices also will change for other mailing services, including standard mail, periodicals, package services, and extra services.
